Setup
- Clean the sandbag to the 'front rack' position across the front of your shoulders or drape it over your upper back.
- Stand with feet hip-width apart, core engaged, and chest upright.
- Ensure you have enough space in front of you for a full stride.
How to do it
- Inhale as you take a controlled step forward, landing with your heel first then the midfoot.
- Lower your hips until both knees are bent at approximately 90-degree angles, keeping the back knee just above the floor.
- Exhale and drive through the front heel to push back to the starting position in one fluid motion.
- Repeat the movement on the opposite leg, alternating sides for the duration of the set.
Form checklist
- Keep your torso upright; do not let the sandbag pull your chest forward.
- Ensure the front knee stays aligned with the second toe, not caving inward.
- Maintain a tight core to stabilize against the shifting sand inside the bag.
- Keep your weight centered; avoid leaning too far forward onto the toes.
Pro tips
- Focus on 'tearing the floor apart' with your feet to maximize glute activation during the drive back.
- If using a front rack position, keep your elbows high to create a stable shelf for the bag and increase upper back engagement.
Make it harder
- Hold the sandbag on one shoulder (unilateral loading) to significantly increase the anti-rotational core demand.
- Add a 2-second pause at the bottom of the lunge to eliminate momentum and increase time under tension.
